How Many Gallons Of Rain Water From Gutter Run Off

Gutters and a downspout.
How many gallons of rain water from gutter run off. A roof of 1 200 square feet in size will collect more water than one that is 600 square feet. Either way you would like to know how much rain has fallen how many gallons have come down from the skies onto your roof yard block or town. You might even want to know how many baths you could get from your rainstorm. Take the dimensions of the footprint of your roof and convert them to inches.
In this example 600 x 240 x 1 144 000 cubic inches of water. An inch of rain is not much but it if falls in half an hour it could flood a gutter. Just a half inch of rain falling on a 1 000 square foot roof will yield 300 gallons of water. The answer is about 623 gallons.
In the form below choose an area s and a rainfall amount to see how many gallons of water fell from the sky onto that area. By this math we are able to catch about 656 66 gallons per inch of rain. Total roof area also affects runoff. To get an idea how much water the roof of your own house might yield use the rainfall harvest calculator above.
